£83.58
The Carlo Gavazzi CTD4X7005AXXX is a robust and accurate solid-core current transformer designed for electrical current measurement, energy monitoring and metering applications. As part of the Carlo Gavazzi CTD-4X current transformer series, it converts a high primary current into a standardised secondary current that can be safely measured by compatible meters, analysers and monitoring equipment.
This current transformer features a 700 A rated primary current and 5 A secondary output, providing a 700/5 A transformation ratio for industrial electrical installations. Its solid-core construction provides dependable measurement performance, while the Class 0.5 accuracy makes it well suited to applications where reliable energy and current measurement is required.
The CTD4X7005AXXX incorporates a generous 51 mm cable aperture and supports busbars up to 64 mm wide, allowing installation around substantial conductors in switchboards, distribution panels and industrial electrical systems. Its practical mounting arrangement and screw-terminal secondary connections support secure integration into new electrical installations and control panels.
Current transformers such as the Carlo Gavazzi CTD-4X reduce high primary currents to a proportional and manageable secondary current for measurement equipment. This allows meters, power analysers, monitoring devices and energy-management systems to measure electrical loads without requiring the full conductor current to pass directly through the measuring instrument.
The CTD4X7005AXXX is particularly suited to higher-current distribution systems where a 700/5 A measurement ratio is required. Its Class 0.5 accuracy, solid-core construction and large conductor opening make it a dependable solution for switchboards, industrial control panels and energy-monitoring installations.
